Brethren of the Common Life

The Brethren of the Common Life (Latin: Fratres Vitae Communis, FVC) was a Roman Catholic pietist religious community founded in the Netherlands in the 14th century by Gerard Groote, formerly a successful and worldly educator who had had a religious experience and preached a life of simple devotion to Jesus Christ. They believed that Christianity should be practiced not only in formal religious settings, but also in everyday life, and they sought to promote a practical spirituality that emphasized personal piety and devotion.
